Abstract In the present study, a modified normalized Bouc-Wen model is adopted to describe the hysteretic behaviour of an O-type wire-cable vibration isolator which exhibits nonlinear elastic stiffness and asymmetric hysteresis dynamic behavior. This paper deals with the parametric identification of O-type wire-cable vibration isolator based on modified normalized Bouc-Wen model. A new simple yet effective two-stage identification method is developed for identifying the model parameters. Numerical simulations and periodic loading experiments were carried out to validate the proposed identification method. The results verify that the proposed identification method is effective and accurate for identifying the model parameters of O-type wire-cable vibration isolator, and the experimental hysteresis loops are close to the identified hysteresis loops.
